A computer-implemented method includes receiving, by a computing system, an update for a computer program executing on the computing system. The method further includes determining, by the computing system, a data structure that is affected by the update by checking a structure change information included in the update. The method further includes checking, by the computing system, instance-count of the data structure, the instance-count representing a number of instances of the data structure in a memory of the computing system. The method further includes based on a determination that the instance-count is zero, applying, by the computing system, the update to the computer program.

A method for heap space management includes, in response to a determination that consumption of a first heap space of an application exceeds a first threshold, determining whether a second heap space of the application after garbage collection is sufficient to accommodate data stored in the first heap space. The method further includes, in response to a determination that the second heap space after the garbage collection is sufficient to accommodate the data, performing the garbage collection on the second heap space. The method further includes storing the data into the second heap space.

The present application relates to a safety prevention and control system and control method of a power battery pack for an electric vehicle. The safety prevention and control system of a power battery pack includes a signal acquisition device, a main controller, and a step-by-step prevention and control execution device. The main controller includes a fault diagnosis device, a cell thermal runaway determination device and a battery pack thermal runaway propagation determination device, which are respectively electrically connected to the step-by-step prevention and control execution device to send different control instructions to the step-by-step prevention and control execution device. The step-by-step prevention and control execution device can execute prevention and control actions of different levels according to the different control instructions sent by the fault diagnosis device, the cell thermal runaway determination device and the battery pack thermal runaway propagation determination device. The safety prevention and control system of a power battery pack for an electric vehicle can provide an active prevention and control measure and a passive prevention and control measure, and according to the actual situation of a specific accident and the prevention and control ability of the prevention and control system, accurately start a prevention and control mechanism, maximize a safety protection effect, and ensure the safety of an electric vehicle occupant.

A remote assistance controller serves as an intermediary between a user requesting remote assistance and a remote assistor. A remote assistance policy determines what the remote assistor can see or not see on the requestor's computer system, and may additionally determine allowed or disallowed actions by the remote assistor. The remote assistance policy may be defined by the requesting user, or can be a default policy for the remote assistance controller. The remote assistance controller generates views for the requestor and for the remote assistor. When the remote assistor requests an operation on the requestor's computer system, the remote assistance controller checks the remote assistance policy to determine whether the remote assistor is allowed to perform the requested operation. When the requested operation is allowed according to the remote assistance policy, the remote assistance controller allows the requested operation, and refreshes the views for the requestor and the remote assistor.
